Description

Technical Field

[0001] This utility model relates to the field of curtain technology, specifically to an anti-bending lower beam system. Background Technology

[0002] Zebra blinds, also known as rainbow blinds or gauze blinds, are a type of fashionable curtain that integrates multiple functions. Zebra blinds are made of small pieces of fabric and gauze of equal width woven together.

[0003] A search revealed that the patent number CN222686562U, entitled "Utility Model of a Curtain Bottom Beam System," includes a U-shaped bottom beam. Research and analysis revealed that although the U-shaped bottom beam has advantages such as being covered with fabric on its outer surface to match the color of the curtain fabric and increase overall aesthetics, it also has the following disadvantages to some extent.

[0004] For example, poor bending resistance can cause the inner round rod of the lower beam to deform when the rainbow curtain is made too wide. This results in noise from the round lower beam hitting the lower beam and friction between the lower beam and the fabric when the curtain is opened and closed. Furthermore, it lacks a cushioning and noise reduction function. When external wind forces act on the curtain, the lower beam is easily affected by the airflow and sways significantly. During this swaying process, the lower beam frequently collides with objects such as walls, furniture, or glass, producing continuous impact noise. This can cause noise pollution in the living environment and interfere with people's normal life, work, and rest. To solve the above technical problems, we have designed a bending-resistant lower beam system. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-bending lower beam system, which has the advantages of being less prone to deformation and having a buffering and noise reduction function. It solves the problems of existing lower beams during use, such as the inner round rod of the lower beam easily deforming when the rainbow curtain becomes too wide, and the lower beam easily producing impact noise when it collides with objects such as walls, furniture or glass.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bending-resistant lower beam system, comprising a lower beam, with first end caps fitted on both sides of the lower beam, and a support column fixedly connected to the opposite side of each of the first end caps. A bearing is fitted on the surface of each support column, and a second end cap is fitted on the surface of each bearing. A round rod is fitted on the surface of the second end cap, and fabric is wound around the surface of the round rod. A limiting groove is integrally formed on the top and bottom of the front side of the lower beam, and a soft gauze fabric is adhered to the inside of the limiting groove using double-sided adhesive. A buffer shell is fixedly connected to the opposite side of each of the first end caps, and a buffer plate is movably connected to the inner cavity of the buffer shell. A buffer block is riveted to the rear side of the buffer plate, and a rectangular groove is formed on the rear side of the buffer block. A rubber airbag is adhered to the inner cavity of the rectangular groove. Springs are bolted to the top and bottom of the front side of the buffer plate, and a partition is fixedly connected to the inner cavity of the buffer shell.

[0007] Preferably, a first limiting cavity is provided at the top of both sides of the lower beam, and a first limiting block is fixedly connected to the bottom of the opposite side of the first end cap, and the opposite side of the first limiting block is inserted into the interior of the first limiting cavity.

[0008] Preferably, a second limiting cavity is provided on the front and rear sides of the top of both sides of the lower beam, and a second limiting block is fixedly connected to the top of the opposite side of the first end cap, and the opposite end of the second limiting block is inserted into the interior of the second limiting cavity.

[0009] Preferably, the front end of the spring is fixedly connected to the partition plate, and the top of the fabric extends through to the top of the lower beam.

[0010] Preferably, dampers are bolted to the top and bottom of the rear side of the partition, and the rear end of the damper is bolted to the buffer plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model has the advantage of being not easily deformed through the cooperation of the first end cap, the support column, the bearing, the second end cap, the round rod, the fabric surface and the limiting groove. During daily use, the round rod is located in the inner cavity of the lower beam. Under the action of the two first end caps and the second end cap, the round rod can be stably supported so that it will not deform, thereby avoiding friction between the fabric surface and the inner wall of the lower beam.

[0013] 2. This utility model has the advantage of buffering and noise reduction function through the combination of buffer shell, buffer plate, buffer block, rectangular groove, rubber airbag and spring. When the wind blows the fabric, the lower beam sways. Since the rubber airbag and buffer block protrude to the rear side of the lower beam, the rubber airbag collides with the object first when an impact occurs. The rubber airbag absorbs the impact force in the first layer. Then the buffer block drives the buffer plate to move forward. The buffer plate compresses the spring and damper, and then absorbs the impact force a second time, thereby avoiding the generation of impact noise. Attached Figure Description

[0021] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0022] Example 1: As Figures 1-6A bending-resistant lower beam system includes a lower beam 1. Both sides of the lower beam 1 are fitted with first end caps 2, which connect to the lower beam 1. The first end caps 2, together with second end caps 5, provide stable support for a round rod 6, preventing deformation. Support columns 3 are fixedly connected to opposite sides of the first end caps 2. Bearings 4 are installed on the support columns 3, further supporting the round rod 6 and ensuring its stability. Bearings 4 are fitted onto the surface of the support columns 3, allowing the round rod 6 to rotate relative to each other, facilitating the opening and closing of the fabric 7. Second end caps 5 are fitted onto the surface of the bearings 4, working together with the first end caps 2 to support the round rod 6, enhancing its stability and preventing deformation. The round rod 6 is fitted onto the surface of the second end caps 5, and fabric 7 is wound around the surface of the round rod 6. The fabric 7, wrapped around the surface of the round rod 6, is a major component of the curtain, enabling the curtain to open and close. The top and bottom of the front side of the lower beam 1 are integrally formed with limiting grooves 8. The limiting grooves 8 are used to bond the soft gauze curtain fabric 9, which plays a limiting and fixing role for the soft gauze curtain fabric 9. The soft gauze curtain fabric 9 is bonded to the inside of the limiting grooves 8 with double-sided adhesive. By setting the soft gauze curtain fabric 9, the beauty and functionality of the curtain can be increased. The opposite side of the first end cap 2 is fixedly connected with a buffer shell 10. The inner cavity of the buffer shell 10 is movably connected with a buffer plate 11. The rear side of the buffer plate 11 is riveted with a buffer block 12. The rear side of the buffer block 12 has a rectangular groove 13. The inner cavity of the rectangular groove 13 is bonded with a rubber airbag 14. By setting the buffer block 12, the rectangular groove 13 and the rubber airbag 14, the buffer block 12 collides with the object first during the impact, and absorbs the impact force in the first layer, which plays a role in buffering and noise reduction. The top and bottom of the front side of the buffer plate 11 are connected with springs 15 by bolts. The inner cavity of the buffer shell 10 is fixedly connected with a partition plate 16.

[0023] The top of both sides of the lower beam 1 is provided with a first limiting cavity 17, and the bottom of the opposite side of the first end cap 2 is fixedly connected with a first limiting block 18. By setting the first limiting cavity 17 and the first limiting block 18, the connection between the first end cap 2 and the lower beam 1 is more stable. The opposite side of the first limiting block 18 is inserted into the interior of the first limiting cavity 17.

[0024] The top of both sides of the lower beam 1 is provided with a second limiting cavity 19 on the front and rear sides. The top of the opposite side of the first end cap 2 is fixedly connected with a second limiting block 20. By setting the second limiting cavity 19 and the second limiting block 20, the stability of the connection between the first end cap 2 and the lower beam 1 is further enhanced. The opposite end of the second limiting block 20 is inserted into the interior of the second limiting cavity 19.

[0025] The front end of the spring 15 is fixedly connected to the partition 16, and the top of the fabric 7 extends through to the top of the lower beam 1.

[0026] Dampers 21 are bolted to the top and bottom of the rear side of the partition plate 16. By setting the dampers 21, the buffer plate 11 moves and the damping effect is further absorbed, thus enhancing the buffering and noise reduction effect. The rear end of the damper 21 is bolted to the buffer plate 11.

[0027] In use, fold the fabric 7 in half and place the bag inside the lower beam 1. Then, pass the round rod 6 through the folded fabric 7 and insert the second end cap 5 into the inside of the round rod 6. Next, install the bearing 4 inside the second end cap 5. Take out the first end cap 2 and insert the support column 3 on the surface of the first end cap 2 into the inside of the bearing 4. Finally, use the first limiting block 18 and the second limiting block 20 to insert the first end cap 2 into both sides of the lower beam 1 to complete the installation. During daily use, the round rod 6 is located in the inner cavity of the lower beam 1. Under the action of the two first end caps 2 and the second end cap 5, it can... The round rod 6 is stably supported to prevent deformation, thus avoiding friction between the fabric 7 and the inner wall of the lower beam 1. When the wind blows the fabric 7, the lower beam 1 sways. Since the rubber airbag 14 and the buffer block 12 protrude to the rear side of the lower beam 1, the rubber airbag 14 collides with the object first during an impact, absorbing the impact force in the first layer. Then, the buffer block 12 drives the buffer plate 11 to move forward, and the buffer plate 11 compresses the spring 15 and the damper 21, thereby absorbing the impact force a second time and avoiding impact noise.

[0028] In summary, this anti-bending lower beam system, through the cooperation of the first end cap 2, the support column 3, the bearing 4, the second end cap 5, the round rod 6, the fabric surface 7, the limiting groove 8, the buffer shell 10, the buffer plate 11, the buffer block 12, the rectangular groove 13, the rubber airbag 14, and the spring 15, solves the problems of existing lower beams during use, such as the easy deformation of the inner round rod when the rainbow curtain becomes too wide, and the easy generation of impact noise when the lower beam collides with objects such as walls, furniture, or glass.
